(01.206-44) My invention is animprovement in a device for protecting packaged material against theeffects of light infiltration. I

My primary object is a window and shield to shut out light, to eliminatefading of garments,

to protect foodstufis, confections, flowers, vegea tables, fruits, andthe like against lightrays caus-. ing discoloration, bleaching, andrancidity when packaged in wrappers, tubes, cartons, boxes or bags fortransportation or display.

In the attached drawings:

Fig. 1 is my device mounted upon away piece of packaging material. l i

Fig. 2 shows a mask mounted on a bag, without a closure shutter.

Fig. 3 is asectional view along the line 3-3 of Fig. 1.

Fig. 4 is closure shutter slide shown in Fig. 1.

Fig. 5 is a sectional View at 5-5 in Fig.2.

Fig. 6 is a sectional View at 66 in Fig. 1.

Fig. 7 is the device adapted to attachment to a broken a cover for abox.

Fig. 8 shows the form applied to a roll or wrapper around a boltofcloth, or uch like articles.

Fig. 9 is a slightlymodified form of the device.

Fig. 10 is a sectional view of Fig. 9 along lines As illustrated:

The device consists of three elements, a mask 13, a transparency l2, anda closure slide I5. The mask I3 is, generally made of some semi-pliantmaterial such as card board with an aperture substantially equivalent toaperture II in a basic fabric ll] of an article. The mask l3 has atransverse slot l4 spacedly above the upper edge of the opening. I l andwider than the aperture l I the transparency I2 is adapted to beadhesively attached to the back of the mask l3 having an unattachedportion l3a providing fora closure area for the passage of a closureslide l5 as indicated bythe dotted lines 1311. The mask is provided withan adhesive extending over the back edge thereof and coveringapproximately to the dotted line 13a, An elongated slidable shutter 15substantially the Width of the slot I4 is adapted toslide snugly throughthe slot l4 and down I3a to below the lower part of the I lar containerfor the transportation or exhibiwindow opening, a mountable mask havingan tion of the contents of the container. In Fi 8 I show its immediateapplication to the packaging of fabrics of various typeswhere'exhibition of contents may be made Without much exposure to thelight. In Fig. 9 I show a slightly modified form wherein the perimeterl8 of the aperture in the basic material is parallel with but slightlyless than the perimeter of the aperture in the mask, providing for adouble protection against the entrance of light into the package.

I claim;

1. The combination with a container having 2.

opening coextensive with the window opening in the body of thecontainer, a transparency covering said window opening having a marginof attachment around the opening, the mask sealingly attached to thecontainer body having an.

unsealed marginadjacent the opening in the mask, a. transverse slot inone end ofthe mask adapted to permit the passage under said unsealedmargin of a window closing shutter, sli-dable window closing shutter. I

2. In a garment storage bag, an-inspection window assembly comprising aframe of sheet material positioned flatly againstthe outside of the bagover an opening in the latter; a transparent panel positioned betweenthe frame and the bag; said panel extending marginally beyond the edges.of the opening in the bag, and said frame extending marginally beyondthe sides of the panel and being adhesively secured to the bag beyondsuch sides; said framehaving an opening therein opposite the opening inthe bag, and said panel extending marginally beyondthe edges of theopening in the frame free from portions of the sides of the frame toprovide confronting guide channels between the panel and the sides oftheframe; said frame having a slot in. one of its ends, which slot spansthe guide channels and is longer than the width of the opening in theframe, and said panel underlying the slot free from that portion of theframe which is disposed between the slot and the opening; and anontransparent closure snugly but slidably positioned between the frameand the panel in said channelsysaid closure' being inserted intothechannels through the slot in the frame and having a portion whichprojects beyond the slot in overlying relation to the adjacentadhesively secured portion of the end of the frame whenthe closuresealingly attached to the back of the mask and covering said opening andslot, a closure slide adapted to be inserted through said slot andpassed downward between the edge of the opening in the mask and thetransparent sheet, and 5 a sealing means on the back of the maskextending over an edge of the transparent sheet.

4. A unitary window for application to a sheet of covering material,consisting of a mask conwindow opening, a sheet of transparent materialtaming a window ope ng, and a slot above said applied.

sealingly attached to the back of the mask and covering said opening andslot, a closure slide adapted to be inserted through said slot andpassed downward between the edge of the opening in the mask and thetransparent sheet, and a sealing means on the back of the' maskextending inwardly beyond the edge of the transparent s eet, saidsealing means comprising the edge of the sheet to which the window isadapted to be R.
